Windows 7 won't boot with Windows Mobile device plugged in/turned on

[DKB]

I have an HP rp5700 system which is connected to a Windows Mobile (6.1) device. If the mobile device is plugged in and turned on, the computer will hang on the HP Event bootup options screen. None of the options will be displayed at the bottom. If I then either a) unplug the device b) undock the device or c) turn off the device, the boot options will appear, and Windows will then boot up without an issue.

I tried changing the boot order, but to no avail. I've also tried unplugging the device, going into BIOS, and plugging the device back in - the BIOS screen gets really, really sluggish until I unplug/undock/switch off the device.

The BIOS is up to date. This doesn't happen with Windows XP Pro, only Windows 7 (Professional, 32-bit). One suggestion I heard was that Windows 7 has issues with connected devices it thinks are USB flash drives (although the device in question isn't in USB mode at the time). I have no other USB devices connected, as the mouse and keyboard are both PS2.

Has anyone seen this behavior before? Did you find a solution?

Solution: get A 64x copy, or Easyer don't connect ur phone when using the pc

So this is definitely a known issue in Windows 7 32-bit? And it's fixed in 64-bit?
